SECIFICATION forming part of Letters Patent No. 619,164, dated February 7, 1899.

Application filed April '7, 1896. Serial No. 586,488. (No model.)

To a/ZZ whom it may' concern:

Be it known that I, PHILIP H. GILBERT, a citizen of the United States, residing at Hazleton, in the county of Luzerne and State of Pennsylvania, have invented certain new and useful Improvements in Trolley-Poles and I do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to certain new and useful improvements in trolley-poles; and it has for its objects, among others, to provide an improved, simple, and cheap pole and trolley by which more satisfactory results are attained and by Ineans of which the ice from the wire can be easily and quickly removed. I provide a ribbed wheel adapted to travel along the wire in advance of the trolleywheel and clear the wire of the ice thereon.

Other objects and advantages of the invention will hereinafter appear, and the novel features thereof will be specifically defined by the appended claims.

The invention in this instance resides in the peculiar combinations and the construction, arrangement, and adaptation of parts, all as morefully hereinafter described, shown in the drawings, and then particularly pointed out in the claims.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification, and in which- Figure l is a view showing my improvements complete and in operative position. Fig. 2 is a face view of the ribbed wheel. Fig. 3 is a longitudinal section through the short pole and its clamp on a larger scale. Fig. 4 is a view of the fork carrying the trolley-wheel, showing its springs.

Like letters of reference indicate like parts which are iiared outward, as shown, and loosely mounted upon its axle.

C are springs secured in the fork of the pole and bearing against the outer faces of the said flanges, as shown, to keep the wheel centered.

D is a short pole forked at the end and adapted to be secured at the other end to the fork E of the clamp F, which is formed in two parts and adapted to be secured to the trolley-pole by set-screws or otherwise, as shown. The connection between the short pole and the fork of the clamp is such as to allow of a limited amount of play or pivotal movement of the short pole, which at its forked end carries the ice-clearing wheel G, which is formed in two like parts, the hubs of which are sleeved upon the axle of the said wheel, which is heldin openings in the forks, and upon their inner or adjacent faces the two parts of this wheel are formed with ribs or projections or analogous provisions H, which will serve to remove the ice from the wire as it travels thereover.

I is a strong spring bearing against the short pole to keep it in contact with the wire, but allowing it to yield in case an obstruction is met, and thus preventing injury thereto.

Modifications in detail may be resorted to without departing from the spirit of the invention or sacrificing any of its advantages.

Insulation may be provided where necessary-as, for instance, under the clamp,whe1e the short pole clamps to the main pole.

What is claimed as new is- 1. The combination with the trolley-pole and the trolley-wheel having flanges flared outwardly, of the springs secured in the fork of the pole and bearing against the outer faces of said iianges, a short pole forked at its end and adapted to be secured at the other end to the fork of a two-part clamp adjustably secured to the trolley-pole, and a connection between the short pole and the fork of the clamp to allowa limited pivotal movement of the said short pole, and the ice-clearing wheel having ribs, substantially as described.

2. The combination with the trolley-pole and the trolley-wheel having iianges flared outwardly, of the springs secured in the fork of the pole and bearing against the outer faces of said flanges, a short pole forked at ingly in Contact with the wire, substantially its end and adapted to be secured at the other as described.

end to the fork of a two-part clamp adjust- In testimony whereof I have lsigned this ably secured to the trolley-pole, and a conspecication in the presence of two subscrib- 5 nection between the short pole and the fork ing witnesses.

of the clamp to allow alimited pivotal movement of the said short pole, and the iee-elearing wheel having ribs, said ioe-clearing wheel Witnesses:

being formed in two parts, and a spring bear- ABNER SMITH,
